Tidal Energy

Definition of Tidal Energy

Tidal energy is energy derived from the movement of the ocean tides.

Water has mass. When it moves, it has kinetic energy which can be harnessed. Kinetic energy is the energy of motion.

What causes tides?
Ocean tides are the response of the ocean to the gravitational attraction of the moon as it orbits the Earth. Tides also respond to the gravitational attraction of the Earth as it orbits the Sun but to a lesser extent.

What is tidal energy used for?
Today, tidal power plants are being built to generate electricity.
